Help picking middle name for Emma.

Amber
I've posted on here before but I think it was in the wrong category. I'm having trouble picking a middle name for Emma. I want to keep it personal if I can but I don't really like the family name choices.. or I love them but they are over used.
Marie, Elizabeth, and jo are family names that almost everyone in my family already has. 
My middle name is Nicole which is a possibility but it sounds really close to my name when said together. 
I've considered Jolie to spice up jo a little.. 
my siblings prefer the name Kate.  
I don't know what to pick or if there's better out there.. my grandmothers middle name is Ann but that sounds plain. 
Please help!
